中文摘要: 地应力与流体的耦合作用是近年来研究的热点,是工程和地质研究中经常遇到的重要课题。因此,寻找简便的求解流固耦合的方法具有重要的意义。本文根据流固耦合方程和热传导方程的对应关系,找出了在一定边界条件下,可用ANSYS中的结构力学模块和热传导模块求解流固耦合方程的简便方法。并将该方法所得结果与理论解和实际结果进行了对比,结果显示他们具有很好的一致性,说明简便方法是可行的。

Abstract:The coupling of the in-situ stress and fluid is the research focus in recent years and also an important subject in research on rock and soil engineering and geology.So it has prominent significance to find out a simple method to solve the stress-fluid coupling equation.In this paper, a simple method of solving the stress-fluid coupling equation at certain boundary conditions is proposed based on the corresponding relation of the seepage equation of stress-fluid coupling and heat conduction equation and using the structural mechanical module and heat conduction module in the ANSYS software.The results obtained from the method are in good agreement with the theoretical solution and actual outcomes.
